Exhaust gas aftertreatment system

An exhaust gas aftertreatment system comprising:

• a distributing housing configured to receive an exhaust gas and a treatment fluid, the distributing housing comprising:
• a distributing housing first panel, and
• a distributing housing second panel;
• a first aftertreatment component configured to receive a first portion of the exhaust gas and the treatment fluid from the distributing housing, the first aftertreatment component comprising:
• a first aftertreatment component first flange configured to be fastened to the distributing housing first panel, and
• a first substrate configured to facilitate treatment of the first portion of the exhaust gas, the first substrate centered on a first component axis;
• and
• a second aftertreatment component configured to receive a second portion of the exhaust gas and the treatment fluid from the distributing housing, the second aftertreatment component comprising:
• a second aftertreatment component first flange configured to be fastened to the distributing housing second panel, and
• a second substrate configured to facilitate treatment of the second portion of the exhaust gas, the second substrate centered on a second component axis;
• wherein the distributing housing second panel is offset relative to the distributing housing first panel in a direction parallel to the first component axis.

An exhaust gas aftertreatment system comprising:

• an introduction housing configured to receive an exhaust gas and a treatment fluid;
• a transfer housing coupled to the introduction housing and configured to receive the exhaust gas and the treatment fluid from the introduction housing;
• a distributing housing coupled to the transfer housing and configured to receive the exhaust gas and the treatment fluid from the transfer housing, the distributing housing comprising:
• a distributing housing first panel,
• a distributing housing first panel opening extending through the distributing housing first panel,
• a distributing housing second panel, and
• a distributing housing second panel opening extending through the distributing housing second panel;
• a first aftertreatment component configured to receive at least a portion of the exhaust gas and the treatment fluid from the distributing housing, the first aftertreatment component comprising:
• a first casing extending through the distributing housing first panel opening,
• a first aftertreatment component first flange configured to be fastened to the distributing housing first panel at least partially around the distributing housing first panel opening,
• a first aftertreatment component second flange, and
• a first substrate, wherein at least a portion of the first substrate is positioned within the first casing;
• a second aftertreatment component configured to receive at least a portion of the exhaust gas and the treatment fluid from the distributing housing, the second aftertreatment component comprising:
• a second casing extending through the distributing housing second panel opening,
• a second aftertreatment component first flange configured to be fastened to the distributing housing second panel at least partially around the distributing housing second panel opening,
• a second aftertreatment component second flange, and
• a second substrate wherein at least a portion of the second substrate is positioned within the second casing;
• and
• a receiving housing configured to receive the exhaust gas from the first aftertreatment component, the receiving housing comprising:
• a receiving housing first panel,
• a receiving housing first panel opening extending through the receiving housing first panel,
• a receiving housing second panel, and
• a receiving housing second panel opening extending through the receiving housing second panel;
• wherein the first casing extends through the receiving housing first panel opening;
• wherein the first aftertreatment component second flange is configured to be fastened to the receiving housing first panel at least partially around the receiving housing first panel opening;
• wherein the second casing extends through the receiving housing second panel opening;
• and
• wherein the second aftertreatment component second flange is configured to be fastened to the receiving housing second panel at least partially around the receiving housing second panel opening.
